SPECIFICATION forming part of Letters Patent No. 600,435, dated March 8,1898. Application filed November 12, 1896. Serial No. 611,877. (Nomodel.)

To all whom it may concern:

Be it known that I, J ONAS G. MATTELIN, a subject of the King of Swedenand Norway, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inCollar-Buttons;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in buttons, and has moreparticular relation to co1lar-buttons.

The object of my invention is to provide a button that will readily passthrough a buttonhole without tearing it and be capable of suchadjustment that after being so passed through it will not accidentallybecome displaced.

The invention consists of certain novel constructions, combinations, andarrangements of parts, all of which will be hereinafter more fullydescribed and claimed.

In the accompanying drawings, forming part of this specification, Figure1 represents a side elevation of a button embodying my invention, thehead of the same being turned in line with the stud or shank. Fig. 2represents a central vertical section through the same, and Fig. 3represents an end elevation of said button with the head turned at rightangles to the shank or stud.

A in the drawings represents the base-plate, B the shank or stud, and Cthe movable head. The said shank or stud B is preferably elliptical inhorizontal section and is either attached to said plate A or cast orstamped integral therewith. The ends of said shank or stud are curved orconcaved vertically, so as to form a reduced portion on said shank inwhich the material of the collar-band and collar will lie when thebutton is applied in position. Said head C is so constructed as tonormally form a continuation of the said shank B and is rounded upon itsupper edges, so as to pass easily through a buttonhole. This head isprovided with a pin 0, that passes loosely through the shank B and plateA and is headed at its lower end to prevent thesaid head C rising offthe top of the shank B.

It will be observed from the foregoing description that when the head Cis turned into alinement with the shank B the said button may be readilyforced through a buttonhole and the said head C then turned at rightangles to the shank B, thus firmly locking the button in position andpreventing its Withdrawal until the said head is again turned intoalinement with the shank. The friction between the pin 0 and the passagethrough which it adjusted position against accidental displacement.

It will also be observed that the elliptical shape of the shank and headapproximates that of an ordinary buttonhole and will permit of said headand shank being forced through the same without in any wise tearing thecorners thereof. When this collarbutton is once applied in position, theconcave edges of the shank B tend to hold the collar-band or collarfirmly in position upon said shank and away from the head C, thusforming an additional means of security. The head 0 has a base contouradapted to exactly meet the outer termination of the said shank and formwith the latter an unbroken continuation, the opposite sides of saidhead being complex and converging toward the uppertermination of thesame.

This button is very simple and cheap in construction and operation andis so formed that it is next to impossible to break the same when incommon use no matter what amount of pressure is exerted upon it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a button, the combination of a base-plate provided with a shank ofapproximately an elliptical shape in cross horizontal section and havingvertical concave edges and also an aperture extending therethrough andthrough the center of the base, a head movably mounted on said shankhaving a base contour adapted to exactly meet the outer termination ofsaid shank and form an unbroken conpasses is suiiicient to hold the head0 in any I tinuation of the opposite sides and edges In testimonywhereof I have signed this thereof, the opposite sides of said headbeing specification in the presence of two subscribconvex and convergingtoward the upper terting Witnesses.

mination of the same, and a pin secured to JONAS G. MATTELIN. the headand extending through the shank, Witnesses: said pin being upset againstthe rear of the O. vMALM,

base, substantially as described. S. A. SANVALL.
